ListBreifStructTemplate

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden of disclosing behavioral traits such as read-only nature, return values, side effects, or authentication requirements. It provides none of these. The word 'List' in the name hints at read-only, but the description itself adds no behavioral information beyond the name.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is one short sentence, but it is under-specified rather than concise. It repeats the tool name and adds no actionable information. It does not earn its place because it conveys almost nothing useful to the agent.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, no annotations, and only two simple optional parameters. The description completely fails to explain what the tool returns, how it behaves, or how it differs from the many similar list/show tools in the sibling list. This is a serious gap for a tool with no other contextual metadata.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has 100% coverage for both parameters (region and project_id), each described as overriding an environment variable. Since the schema already documents these parameters fully, the description is not required to add more. The baseline of 3 is appropriate; no extra semantics are needed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description merely restates the operation name: 'Huawei Cloud LTS operation ListBreifStructTemplate.' It gives no information about what the tool actually does—whether it lists templates, retrieves details, or performs some other action. The generic 'Huawei Cloud LTS operation' does not distinguish it from siblings like ListStructTemplate or ShowStructTemplate.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No usage context is provided. The description does not state when to use this tool versus alternatives, nor does it mention any prerequisites or exclusions. Given the many sibling tools with similar names, the lack of any guidance leaves the agent uncertain about selection.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
